asyncnoter: fix bug, don't show notetime textfield when the user does the following
1. Start editing
2. Press enter to end editing (textfield still focused!)
3. Click anywhere (=> textfield loses focus => causes .toggle() => shows textfield again)
asyncnoter: fix editing the time to or from `00:00:00`
asyncnoter: deleting and adding bug caused by ShareJS bug with invalid `child op` path..
